Ok, so there are custom garage doors that implement “switch” - so On is Open and Off is closed. My garage door (switch) shows up in the Routine chooser for turn on/off switch option, but like others noted above I can’t select it when I go down the “open/close garage door” path, since it’s not showing up as an option.
See Linear GD00Z-4 GD00Z-4 Z-Wave Garage Door Opener-- for some of the device types that also work like switches.
